RAIL-JOINT.

Specification of Letters Patent.

' xatented AQgHBO, 1907.

Application filed January 30, 1907. Serial No. 354.79%.

ence being bad therein to the accompanying drawing.

I his invention relates to rail joints, and the invention has for itsobject to provide a novel rail chair for sup porting the confrontingends of two sections of rails.

Another object of this invention is to dispense with the use of boltsand nuts in connection with fish plates, for holding the confrontingends of two sections of rails together. I

With these and other objects in view, which will more readily appear asthe invention is better understood, the same consists in the novelconstruction, com-.

bination and arrangement. of parts to be hereinafter more fullydescribedand then specifically pointed out in the appended claims, and referringto the drawing forming part of this specification, like numerals ofreference designate corresponding parts throughout the several views,.inwhich:-- I

Figure 1 is a perspective view of my improved rail joint, Fig.2 is aplan of the same, Fig. 3 is a cross sectional view taken on the line x-xof Fig. 2, and Fig. 4 is a horizontal sectional view of a portion of therail joint illustrating one of the pins or keys thereof. My inventionconsists inproviding a rail chair having a base 1 and integral fish bars2, said bars being adapted to brace the heads 3 and web portions 4 ofrails,5 and 6 mounted in the chair.' The rails 5 and 6 to belconnectedtogether are placed endwise within the chair and to secure the endstherein, I use headed pins-7, said pins passing through openings 8foriiied in the fish bars 2 and openings 9 formed in'the web portions4of the rails 5 and 6.

i To retain the pins 7 in the openings 8 and 9; I fifo vide the pinswith elongated slots 10 to receive wedge.- shaped keys 11. To preventthe pins 7 fi'om rotating and to insure a more positive locking of thepins and keys 11, I provide the fish bars 2 with grooves 12 to re ceivethe beveled edges of the wedge shaped keys 11. By the novel manner inwhich I secure the rails within the chair, longitudinal displacement ofsaid rails is practically impossible, andit isobvious that one railcannot become laterally or vertically displacedwith relation to itsadjoining rail. I

The sides of the chair are provided with vertically disposed slots 14for spikes, the slots upon one side of the chair being staggered withrelation to the slots upon the opposite side. While spikes may be usedfor securing a chair to a tie, other means may be employed which willfirmly hold the chair upon the tie and prevent its creeping thereon. I

The chair which constitutes a part of my invention is preferablyconstructed-of strong and durable metal to withstand the vibratorystrains and stresses to which it is subjected by rolling stock passingover the rails, mounted within the chair.

Such changes in the size, proportion and minor details of construction,as are permissible by the appended claims, maybe resortedto withoutdeparting from the spirit and scope of the invention.

WhatI claim and desire to secure by Letters Patent,

In a rail joint, the combination with rails, of avchair adapted toembrace the contiguous ends of said rails, comprising a base andintegral iish bars, said fish bars having openings formed thereinadjacent their ends, and provided at their lower edges with grooves,headed pins adapted'to pass through said openings and through fish-baropenings in the webportions of said rails, said pins havingelongatedslots formed therein having one wall of the slots at an angle to theother wall, and separate wedge keys adaptedto pass through said slot,said keys having their sides adjacent'the fish plate formed at an anglecoinclding with the angular wallet said slot and fitting in groovesformed in said fish burs, substantially as de scribed. v

In testimony whereof I aflix'rny signature in the presence of twowitnesses.
